'can't find gem rails - Gem::GemNotFoundException

Using ubuntu 10.04, rvm. At first, I've installed ruby 1.9.2 with rvm, gem rails and generated some new project and started it successfully. Everything was working fine. But after changing to another project, executing bundle install command (output looks OK) and starting rails server - error occurs:

rails s

/home/jacek/.rvm/rubies/ruby-1.9.2-p318/lib/ruby/site_ruby/1.9.1/rubygems.rb:316:in `bin_path': can't find gem rails ([">= 0"]) with executable rails (Gem::GemNotFoundException)
from /home/jacek/.rvm/gems/ruby-1.9.2-p318/bin/rails:19:in `<main>'

gem list rails

Solution 1:[1]

For me just installed bundler. This makes everything work again.

gem install bundler --no-ri --no-rdoc

Solution 2:[2]

You can switch version between Ruby with $ rvm use --default 2.4.0 for example

But for your problem try this :

  1. $ gem install bundler

  2. $ gem install rails

Hope it helps !

I think below command will work

gem pristine rails
